upgraded to big brake kit now need help

[klodkrawler05]

Over the past week, thanks to a really good price from Mike at Hilbish I was able to get my stock 10” front disc, rear drum brake setup upgraded to the Ford Racing rally brake kit. the kit is the front brake setup from the 05 up and the svt rear setup so I now have 11” front and rear discs.
I had the conversion done at the stealership since the car was already there getting work done and it wasn’t much more to have the brakes thrown on. But when I got the car back the brakes are extremely spongey for the first maybe 1/3 of the pedal travel. Its not that the brakes are lacking stopping power because there is plenty of that what I’m wondering is why a very large part of the pedal travel seems to have no brake response but the remaining 2/3 of travel has more than enough my old brakes were very progressive from just about as soon as you touched the pedal but these brakes have nothing but then once you get halfway through the pedal its just like normal.
I took my car right back into the dealer but they said that the brakes were most definitely completely/correctly bled and that it was because I had upgraded a non 4 wheel disc car to not only 4 wheel disc but also bigger than stock disc they suggested trying to figure out if there was a different master cylinder I could install that would give me more braking.
So heres where I need the help of you focus brake gurus will changing/upgrading my master brake cylinder fix my lack of “initial bite?” remember its not that I don’t have full braking power because I have more than enough I’d say about 35% more braking than my old setup even with ebc components I just want the brakes to start functioning right when I hit the pedal I don’t want to have to push the pedal halfway in to make a slow stop.
Any help is appreciated!
Thanks

make sure that they are bled properly. Probably wouldn't hurt to put new fluid in there entirely and power bleed them. That "should" solve your issues.

My brakes are a little spongy but not a 1/3 of the pedal.

If you pump the brakes do they get firmer? Or stay spongy?

[klodkrawler05]

they stay spongy but they do get a little better better

Hmmm. Idaknow then. Thinking either you master cylinder has some minor leaking around the seal or your new brakes require a larger master cylinder (new brakes require more volume?). Will have to refer this one to the brake experts. Just a thought. They did redo your brake bias right?

You have a 2000. Chances are, your brake hoses could be a lil worn. I don't know about your finances but I think you could possibly fix that issue with stainless steel lines. I upgraded my 2000 Kona with the svt brakes all the way around. The pedal is a lil spongy but nothing terrible. I want stainless lines to correct the issue as well.

As was previously stated I would look into the brake bias on the car due to the fact that it used to have rear drums. I am not sure if the car has a proportioning valve but that could be the problem. But I would bleed the brakes your self and see what you find.

the reason i had big brakes put on is because a tierod snapped and caused 3000 worth of damage and it wound up only costing 200 more to do all big brakes vs having ford put on oem stuff so i'll keep the brake line thing in mind once i've got some cash built up again
